To (Ml whom it may concern.-

Be it known that I, PERRY C. SMITH, a citizen of the United States, residing at Chicago, in the county of Cook and State-of Illinois,

5 have invented certain new and useful Improvements in Bread-Mixers, of which the ollowing is a specification.

This invention relates to improvements in bread and other dough mixers; and the ob- Io ject of the invention is to provide a device which will be easy to put together and to take apart, which will be easy to operate, and which will be efficient and thorough in mixing together the ingredients of the dough.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in Which Figure 1 is a vertical central section of my invention on the line 1 1 of Fig. 2. Fig. 2 is a top plan view of same. Fig. 3is an elevation of my device, showing the side wall broken away in part and some of the parts in vertical section; and Fig. 4 is a perspective view of the removable base for en aging the pail and 2 5 for clamping the mixing device to a table or other support.

Like characters of reference indicate like pprts throughout the several views of the avvings.

5 is a pail, preferably of tin or other sheet metal, circular in cross-section and with the usual sli ht downward taper. The pail has the wire edges 6 at top and bottom to increase the security of the attachment to the 3 5 pail of the base-support and support for the mixing-rod.

7 is a base-plate having the two diverging arms 8, which arms terminate with hooks 9 to engage the bottom head 6 of the pail. The

plate has the pair of cars 10, between which the cam 11 is pivotally mounted. The cam 11 has the handle 12, by which it is manipulated. Bylowering'the handle 12 to ositlon shown in Fig. 3 the cam is turned so t e bead on the bottom of the bucket will pass the cam.

Then by raising the lever the cam will be moved into clamping position upon the bead. Integral with the plate 7 is the hanger 13, having a horizontal terminal portion with a 5 vertical threaded hole through which the setscrew 14 is screwed. The screw '14 will referably have the wings 15 at its outer en and the bearing-plate 16 at its inner end and in conjunction with the plate 7.will form a clamp 5 5 for fastening the apparatus to the table.

Located upon the toppf the pail is the plate 17, (see Fig. 2,) having the two diverging arms 18, which terminate with hooks 19 for engagement with .the top head of the ail in the manner shown in Figs. 1 and 3. T e opposite end of the plate from said arms isbent down around apin 20, which supportsa cam-- 22, and around said hole on the upper side of the plate is the sleeve 23, having a lateral flange through which the sleeve is riveted to the plate. Formed out of the material of the plate and extending upwardly in a circle around the above-mentioned opening is the owered the cam ocks the-platerib 24, having the lateral branches 25 extending longitudinally of the plate and each of the diver ing arms.

26 is the heater and mixer-rod, which has the fixed sleeve 27 mounted on its upper end. The sleeve 27 makes a close Working fit in the opening through the plate 17. It has lateral flange 28 terminatin with the upwardlybent portion 29, together forming a cup-like holder to receive the flange 22 and to catch any di'iplpings of oil or other objectionable matter t at might work down through the bearings and drop into the dough mixture. The upper end of the sleeve 27 is squared to receive the crank 30, by means of which the mixer-rod is rotated. A wing-nut 31 is screwed upon the threaded end of the rod 26 i to hold the crank in place and also to draw.

the parts together in a ropcr working fit.

In order to remove the mixer-rod from the plate 17 it is necessary to screw oif the wing nut 31, and as this removal or 'se aration of the parts is necessary every time t e machine is cleaned there is constant danger of the nut getting lost. t e operations more simple, I construct the nut so it will be inseparable from the crank. This is accomplished by reducing the tolilpart of the opening through the handle, as s own at 32, Figs. 1 and 3, and forming a sleeve on the under side of the'nut for insertion through the reduced opening. Then after the sleeve is inserted its end is swaged out to form a lateral flange 33, which prevents the withdrawal of the nut from the crank, while allowing-the To prevent this and to make an obliql and unscrewing.

The crank has the knob or handle 34 at its outer end for use when the dough is stiff and a like handle 45 ad'acent to the mixerrod for use when the wor is light and a quick movement is desired.

The particular shape of my mixer-rod, as shown in Fig. 1, is important. The rod is bent at an obtuse angle 35 and extends thence in e downward direction nearly to the side wa of the pail and to or a little below the middle depth of the pail. Then it is bent on a curve 36 and extends downwardly and laterally of the oblique portion in a part '37, curved on a longer radius to the bottom corner of the ail, where it is bent upwardly, this time at su stantially a right an e 38 and ex-' tends parallel with the side of t e pail and in close relation to said side for a short distance. It is finally bent on a curve 39 and extends in a straight portion oblique to the vertical and upwar 1y to near the center of the pail, where it terminates at a sufiicient distance from the 0 posite obli ue member to permit the mixed dou h to be easily. stripped ofi over this free en All parts of" the mixer-rod lie substantially. in the same vertical lane, and the rod is" 'ven the shapehere escribed in order that its arts will traverse substantially all parts' g of t e pails interior and thoroughly stir and mix the ingredients placed within the pail. The lower angular bend 38 enters the bottom corner of the pail and prevents the accumulation therein of unmixed portions.

Having thus fully described my invention, what I e aim as new, and wish to secure by Letters Patent, is

1. In a bread-mixer, a pail, a mixing-rod having a vertical top portion which merges into a downward oblique portion, said ohhaving lique portion merginglinto a curved bend adjacent to the side of t e pail, and thence into a part which extends across the pail and is formed with an upward angular bend at the lower corner of the pail, said rod extending thence upwardly adjacent to the side of the pail'andthence in an oblique upward direction toward the middle of the pail, and means for rotatin the rod.

2.- In a readmixer, .a pail, a mixing-rod a vertical to portion and a portion exten ing downwar y therefrom to near the side of the pail above the bottom of the pail and thence across the pail to the lower corner thereof, thence upwardly ad'acent to that side ofthe pail andthence ob 'quely toward the middle of the pail, and means for rotating the I'Qd; I p 6 3. In a bread-mixer, a pail, a plate across the to of the pail, a gmixing rod assing throng an opening in the plate and aving its lower end bent to do the mixing when the ing a lateral flange operatin it a ainst the under side of the plate, said sleeve passin through the plate and having its upper end squared to receive a crank, a crank on said squared end of the sleeve and a nut on the threaded u per end of the rod to draw the parts toget er and secure them against removal.

4, In a bread-mixer, a pail, a plate across the top of the pail having an opening over the middle of the pail with an under side flange around said opening, a mixing-rod passing through said opening said rod having its lower end bent to do the mixing when the rod is rotated, a flange extending laterally of the portion forming an annular receptacle to receive said flange on the late, a crank on the thg plate between the crank and flange on the re r 5. In a bread-mixer, a pail, a plate across the top of the pail having a hole centrally of' the pail, a mixing-rod having a straight art passing through the hole said 'rod being ent downwardl and laterally and continued to near the si e of the pail and then bent downwardly and in opposite lateral direction and continued to the opposite lower corner of the .pail' and then bent upwardly and continued parallel with the side of the pail and then bent inwardly and upwardly and terminating near the middle of the pail, a sleeve fixed to the rod where it passes through the plate said sleeve having a flange adjacent to the under side of the plate with an upper channel to receive a flange on the under side of the plate, a crank on the squared upper end of said sleeve and a nut on the threaded end ofthe rod to draw the parts together and retain them.

6; In a bread-mixer, a pail, a plate crossing the top of the pail having an opening at the middle of the pail, a bent mixing-rod having astraight portion passing vertically through the opening in the plate a crank above the plate to rotate the rod, a nut on the threaded end of the rod to retain the crank, and means for uniting the nut and crank whereby the two are inseparable but, the nut is revoluble independently of the movement of the crank.
